This model is furnished with wheels and
handles.Wheels,handles,andthemounting
hardware are found in the shipping carton.
3. Place heater on wheel support frame.
Make sure air inlet end (rear) of
heater is over wheels. Line up holes
on fuel tank flange with holes on
wheel support frame.
WARNING: Use only kero-

of fire or explosion. Never use
gasoline, naphtha, paint
thinners, alcohol, orotherhighly
flammable fuels.
TOOLS NEEDED
• Medium Phillips Screwdriver
• 3/8" Open or Adjustable Wrench
• Hammer
4. Place handles on top of fuel tank
flange. Insert screws through handles,
fuel tank flange, and wheel support
frame. Attach nut finger tight after
each screw is inserted.
Do not use heavy fuels such as No. 2 fuel oil
or No. 2 Diesel. Using heavy fuels will
result in:
1. Slide axle through wheel support
frame. Install wheels on axle.
5. After all screws are inserted, tighten
nuts firmly.
IMPORTANT: When installing wheels,
point extended hub of wheels toward
wheel support frame (see Figure 2).

IMPORTANT: Use a KEROSENE ONLY
storage container. Be sure storage container
is clean. Foreign matter such as rust, dirt, or
water will cause the flame-out control to

derstand the warnings in the
Safety Information section, page
2. They are needed to safely op-
erate this heater. Follow all local
codes when using this heater.
The Fuel System: The air pump forces
air through the air line. The air is then
pushed through the burner head nozzle.
This air causes fuel to lift from the tank.
A fine mist of fuel is sprayed into the
combustion chamber.
5. Plug extension cord into standard 120
volt/60 hertz, three-hole, grounded out-
let.Adjust thermostat to desired setting.
If heater does not start, thermostat set-
ting may be too low. Turn thermostat
knob to higher position to start heater.
If thermostat is in HIGH position and
heater still will not start, push in flame-
out control reset button (see Figure 4).
Note:Acold heater may affect the ther-
mostat setting. This thermostat is a gen-
eral-heating control. It is not intended
for precise temperature control. Adjust
thermostat until heater cycles at the
desired setting.
The Air System: The motor turns the fan.
The fan pushes air into and around the
combustion chamber. This air is heated and
provides a stream of clean, hot air.
TO START HEATER
1. Follow all ventilation and safety
information.
2. Fill fuel tank with kerosene or No. 1
fuel oil.
The Ignition System: The electronic
ignitor sends voltage to the spark plug. The
spark plug ignites the fuel and air mixture.
3. Attach fuel cap.
4. Plug power cord of heater into three-
prong, grounded extension cord. Exten-
sion cord must be at least six feet long.
The Flame-out Control System: This
system causes the heater to shut down if the
flame goes out.
